Enable Query Cache is the appropriate short-term performance optimization for a frequently accessed Tableau Next dashboard. Query caching reduces repeated execution of expensive live analytical queries by temporarily reusing previously calculated query results.
Salesforce specifically positions dashboard query caching as a mechanism to accelerate page load times for frequently visited dashboards. Current Tableau Next functionality can store and reuse query results for up to approximately 30 minutes, thereby reducing system overhead and improving the end-user experience.
This is precisely appropriate when the consultant wants a rapid tactical improvement before investigating deeper issues such as semantic-model complexity, source performance, query design, data architecture, or excessive dashboard density.
Disabling Reflow concerns dashboard layout behavior and responsive presentation rather than query-processing latency. Turning off Tableau Agent likewise does not address the underlying query execution performed to render dashboard widgets.
Caching does involve a freshness tradeoff because viewers may temporarily receive cached rather than newly executed query results. For dashboards requiring immediately current information, live mode may still be necessary. The consultant should therefore treat caching as a deliberate performance-versus-freshness decision.
